Characterizing property (NL) in {C}oxeter groups

Sahana Balasubramanya, Rachel Niebler, Roberta Shapiro

A group has Property (NL) -- which stands for ``no loxodromics" -- if no element of the group acts loxodromically on any hyperbolic space. In this brief note, we provide a complete…

Hyperbolic actions of Thompson's group and generalizations

Sahana Balasubramanya, Francesco Fournier-Facio, Matthew C. B. Zaremsky

We study the poset of hyperbolic structures on Thompson's group and its generalizations for . The global structure of this poset is as simple as one would expec…

Stable subgroups of graph products

Sahana H Balasubramanya, Marissa Chesser, Alice Kerr +2

We extend the characterization of stable subgroups of right-angled Artin groups of Koberda, Mangahas and Taylor to the case of graph products of infinite groups. Specifically, we s…

The semi-simple theory of higher rank acylindricity

Sahana Balasubramanya, Talia Fernos

We present a new notion of non-positively curved groups: the collection of discrete countable groups acting (AU-)acylindrically on finite products of -hyperbolic spaces with ge…

Acylindricity in Higher Rank, Part I : Fundamentals

Sahana Balasubramanya, Talia Fernos

We present a new notion of non-positively curved groups: the collection of discrete countable groups acting (AU-)acylindrically on finite products of -hyperbolic spaces with ge…

(Non-)Recognizing Spaces for Stable Subgroups

Sahana Balasubramanya, Marissa Chesser, Alice Kerr +2

In this note, we consider the notion of what we call recognizing spaces for stable subgroups of a given group. When a group is a mapping class group or right-angled Artin group…
